There are two popular CoinMarketCap namely; https://CoinMarketCap.com and https://Coingecko.com. Both CoinMarketCap and Coingecko have both web apps and mobile apps. And they've been in the space for a longer time.
The apps recently introduce daily Diamonds and Candy which can be redeemed with NFTs, Discount, or other tokens. CoinMarketCap recently introduces its swap App which you can now swap app through CoinMarketCap using the Pancakeswap and Uniswap API.
However, the MarketCap mobile App I use is Dopamine which can be downloaded on PlayStore. The App is still in an early phase and the developers are working on it every day. Dopamine has some features you would love like Currency Converter, News, Top Crypto Youtubers, and has DeFi wallet integrated into it. What's good about Dopamine is that it has both Coinmarketcap and Coingecko incorporated into the app. Some tokens are only listed on Coingecko and cannot be found on CoinMarketApp but if you search for such token on Dopamine you will find it over there.
Download Dopamine from the PlayStore and explore it to see if you will love it.
Have a great day!
